In carrying my invention into effect I provide a locking strip or body having one or more segmental or laminated surfaces formed either by the assemblage of a multiplicity of leaves, segments, parts, or by incisions or grooves cut in one or both side faces of a body, or by folding a sheet uponitself a number of times so that the exposed edges formed thereby are segmental.

In the use of the strip or body, the flexible or yieldable segments or parts thereof are normally arranged at right angles to the surfaces to be coupled together or at a slight angle of inclination, and are forced into an opening or space between the parts which is less than the vertical dimensions of the lock strip or body, whereby the segments or parts are flexed backwardly away from the direction of engagement in sliding the two parts together in the operation of coupling the same, thus moving said segments, laminations or parts into a slight angle with reference to the engaged surfaces, at which angle the segments form a series of wedges which resist return movement by edgewise stability and crushing strength of the segments and the lock strip or body as a whole, it being understood that suitable means will be provided for supporting, at least temporarily, the lock strip or body in engagement with one ofthe parts to be coupled getlier, and this may be done by slightly grooving one of said parts.

lt will be understood that my improved lock strip is adapted for use in coupling two or more bodies of any kind or class together, regardless of the nature, texture or material employed in said bodies. ln the accompanying drawing, l have shown, for illustrative purposes, only a few methods of carrying my invention into effect, and while l disclose one or more forms of lock strip in the several uses described, it will be understood that any form of lock strip disclosed or coming within the scope of my invention may be employed in the many uses thereof.

ln Fifi: l of the drawing, l have shown at 23 atrame member composed of channel iron which may constitute a frame member of apparatus of any kind or class, or the structural frame of a. building or other body or steel structural assemblage. At 24, l have represented another metallic or ther body coupled with the body 23 by placement within the channel thereof and by the use of substantially rigid lock strips L arranged at the inner end of the body 2aand other more eXible lock strips l) arranged outwardly of the strips a. The strips a; and b are arranged on the upper and lower surfaces of the body 24- and operate upon the inner faces of the top and bottom flanges 23 and 23) of the frame part 23. lVith this construction, a lad c of cushioning material is placed at the inner end of the body 2lto allow for the firm engagement of said parts 23 and 2.4L, and the movement of the lock strips ci and Z) from a position at right angles to their adjacent surfaces to a slight inclination as seen in the drawing, thus preventing backward movement or separation of the parts 23 and 2e. In the construction described, the strips t may be composed of metallic segments to form a strong and durable connection where the greatest strength of the parts coupled together is desired, whereas the strips b may be composed of more yielding and resilient material such as paper, cardboard, fibre, rubber and the like or a combination of such materials and metal. ln coupling the parts together, the strips ci and Z) may be retained in connection with either parts gel-2l, prefer-a ly the part 23, by a suitable glue which wi l temporarily retain the parts in position to permit of the coupling of the body or part QY-l with the frame part Q3. lt will also be understood that whilD l have described the part 23 as being composed of steel, it may be metal of any nature or structure whatever.

ln Fig. 2 of the drawing, l have shown a modification, wherein the parts 23 and 24 are coupled together by pairs of lock strip sections (Z and e arranged on the upper and lower surfaces of the part in the same manner as the arrangement of the strips a and b but the section CZ is composed of a plurality of segmental lock strips Z2 arranged at an angle of substantially forty-five llegrecs to the longitudinal plane of the part 2er, where the section e has a series of similarly arranged lock strips e2, the angle of inclination of which is opposed to that of the section (Z. lVith this constiuetion,'side wise or lateral movement of the parts 23 and 24 witlrrelation to each other is obviated, as well as endwise movement of the part 24 with relation to the part 23.

ln Fig. of the drawing, l have shown two angle iron parts 25 and 2G coupled together by two lock strips arranged on the outer faces of the flanges 25#L and 25 of the parts and 26 and within a U-sliaped keeper or clamp 2T. Arranged between the adjacent faces of the flanges 25 and 26"L are two rubber pads 28-28"L between which is disposed a sheet metal retaining member 29 i iaving side flanges 29 which operate in conjunction with the rubber sheets Z8-28a to retain the parts 25 and 26 against lateral movement and to provide a friction coupling between said parts. In this form of construction, it will be understood that the lock strips and will be made to compensate for the compression and resiliencv of the rubber strips employed. i

ln Fig. il; of the drawing, l have shown a bracket 30 coupled with a channel frame body Q3 similar to that shown in Figs. l and Q, by means of a U-shaped keeper or clamp 2T similar to the clamp shown in F ig. 3. ln this construction, one lock strip f3 is arranged between the lower flange 23h of the frame and one side of the clamp 27, andanother lock strip ft is arranged betweenthe other side of the clamp and the end face of the bracket 30. A pad of rubber or other resilient material 23 is arranged between the upper face of the bracket 3() and the flange 23h.

In Fig. 13 of the drawing, I have shown resilient segmental strips preferably arranged in a plurality of sections g disposed between adjacentedges of two boards, slabs or parts 31 and. 31n which may be mounted in connection with a suitable support 32. In this use of my invention, the strips g operate as joints filling the space between the parts 3l, 31aL and forming expansion joints therebetween. One illustration of this invention would be the provision of such joints between wall boards or slabs used in building construction, but of course, many other uses may be made thereof. The resilient segmental strips arranged in the sections g are of a width greater than the width of the space between the parts or wall boards 31 and 31a, and of a thickness equal to the thickness of said boards. The sections g are placed in position by sliding the same downwardly over the wall or support 32 and between the boards 31 and 31a, and in this operation the separate strips of said sections flex upwardly at their ends, and in this manner compensate for any expansion or contraction that may exist between the boards 31 and 31a. o

In Fig. 14, I have shown lock strips t disposed between the side or peripheral edges of a panel 33 mounted in a frame 33a for retaining the panel 33 against displacement. In this use of the invention, the panel may constitute a mirror, glass or a. wood, metallic or other body of any kind or class, it being understood that the panel 33 seats on a back wall or flange portion 33b limiting its inward movement, and is checked against outward movement by the lock strips b employed.

In Fig. 17 of the drawing, I have shown two metallic frame members 34 and 34 employed in common abutting` or en dwise relation. In the construction shown, said frame members are of I-beam cross sectional form as seen in the cross sectional view in said figure. In this construction, a coupling member 3&9 encircles the frame parts 34 and 3stLL whereby they abut, and coupling strips z' are arranged between the outer and inner surfaces of the top and` bottom flanges of the parts 31h-34@ and the corresponding surfaces of the coupling 34" as clearly seen in both views of said figure. rlhe angular arrangement of the strips is shown in the gure to the right, the strips engaging the frame part being at an angle opposite to that of the strips engaging the frame part 34?, thus preventing endwise separation of the parts. y

In Fig. 1S of the drawing, I have shown a body 35 of any kind or class coupled with a channel body or frame 23 by providing the end of the body 34 with a lock strip structure secured in any desired manner to the end of said body 35 and projecting at opposite faces thereof to form flexing portions la? which engage the inner faces of the top and bottom flanges 23a and 23b in coupling t-he body 35 with the frame part 23.

In Fig. 19 of the drawing, I have shown a lock strip am mounted ina recess 36 in a part 36a adapted to be coupled with a channel frame 23. In this construction, the lock strip m is retained in definite relation with reference to the part 36a and flexes with relation to both parts in coupling the same together. It will be understood that the depth of the recess 36 may be very shallow in many uses of the invention, and contrasting cia-ily in sheet nietal structural work.

In the several uses of the invention herein disclosed, as well as in many other uses of the invention in coupling two parts or bodies of any hind or class together, it will be understood tl at I may employ any one of the coupling strips bodies or segments herein disclosed, or coming within the scope of my invention, and where the reference characters c to vm inclusive are given, it Lwill refer to anyone of niy improved coupling devices that may be suited for the purpose intended. A few forms of these devices are shown in Figs. to 12 inclusive, 15, 16, 20, 21 and 22.

In Figs'. 5 and 6 of the drawing, I have shown one form of lock device 37 which is composed of a unit body, the opposite side aces of which are cut or subdivided longitudinally to form a plurality of resilient segments 37a. As seen in Fig. 6 of the drawing, these segments are again divided by widely spaced transverse cuts 37b to divide said segments into transverse rows 37C. It will be understood that the body 37 may be composed of rubber, paper or any other suitable material. The central portion of the body will operate as a binder, retaining the segmental side portions together.

In Fig. 7 of the drawing, I have shown a lock strip or device 38 which is composed of a plurality of comparatively thin strips, sheets or segments which may be of any desired length, depending upon the specific use of the device and stacked into a desired width. It will also be understood that the depth of the respective segments may be arranged to suitthe particularuse thereof.

If desired, these segments may be retained in stacked relation by a binding'strand or strip 33a. Each strip segment or part of the device 38 may be composed of metal,

wood, fibre, paper, rubber or any other de-r sired material., or a combination of such inaterials, or an alternate arrangement of different materials may be employed, for example as seen in Fig. 11 of the drawing, wherein a device 39 is provided with segto that shown in said; figure and espe-k llO iso
